Kitsuke Practice with Sha Hikizuri

My newest hikizuri arrived in the mail this past week. I suspect it to be one that was used for dance/stage performance, and by the incredibly large dimensions (235cm long and 150cm wingspan!), it might even have been used by an onnagata.

Not only its size is intriguing, but the lining is also a bit of a mystery. It's sha-awase for the most part, but it is unlined at the top of the shoulder area.
